INTRODUCTION

The era of networked space communications is slowly dawning across ESA (European Space Agency), NASA (National Aeronautics and Space Administration) etc.

All the major space organizations and industrial partners have been working together as part of the Consultative Committee for Space Data Systems

The first goal will be to let astronauts communicate among themselves, with control centers on Earth, and with spaceships and base stations

The gateways: The special purpose satellites connecting the earth’s internet with the network of another planet

A 'bundle protocol' is needed because the IPN will not be able to communicate in real-time due to the large travel distances

The present scenario

JPL (Jet Propulsion Laboratory) has performed a conceptual study of a proposed Mars Network and the required satellites.

The satellites are

• Microsats: for communication around Mars using small satellites

• MARSat: Larger Mars Aero-stationary Relay Satellites, more capable MARSat satellite acting as a higher bandwidth gateway to Earth

PHYSICAL CHALLENGES

Large distance

The time delay between request for and receipt of information

Interactive protocols do not work

Page 9: Internet in space

TECHNICAL CHALLENGES

power consumption by the various nodes in the system

servicing of broken hardware

orbital dynamics - the problems that arise when the sun is between two points that wish to communicate

THE FUTURE

The IPN will vastly simplify the communications element of future space exploration missions.

aiming to be fully implemented between 2020 and 2040

primarily in the moon and the mars

NASA has plans to make this gateway accessible to the public as much as is possible. However, this capability will demand security of the highest order.

CONCLUSION

Ultimately, we could see a space borne internet that could revolutionize how people

work in outer space, just as the internet is changing our Earth-bound life.

People who surf the Internet today and tap websites in extreme locations such as

Antarctica may someday be able to communicate to web or servers on Martian

microsatellites to request data directly from Mars
